CPT® Code 95912

Nerve conduction studies (NCS) are diagnostic tests utilized to assess the functionality of peripheral nerves. These studies are particularly important for identifying nerve damage and various nerve disorders, including conditions such as carpal tunnel syndrome. Patients may present with symptoms like numbness, tingling, or other abnormal sensations, which can indicate underlying nerve issues. During the procedure, several flat metal disc electrodes are affixed to the skin using adhesive paste or tape. A shock-emitting electrode is strategically placed over the nerve being evaluated, while a recording electrode is positioned over the muscles that the nerve innervates. The test involves sending electrical pulses through the shock-emitting electrode, which stimulates the nerve. The response is measured in terms of conduction time, which is the duration it takes for the muscle to contract following the electrical stimulus. Additionally, the amplitude, or strength of the muscle response, along with the speed of the response, is recorded, reflecting both latency and velocity. After the completion of the studies, the physician analyzes the recorded data and compiles a comprehensive written report detailing the findings. This code, CPT® 95912, specifically pertains to the performance of 11-12 nerve conduction studies, with other codes available for varying numbers of studies conducted.
